e The principal object of this invention is to make` a common singleacting liftpuml)l serve not only the ordinary usesfof a wellri l pump,but also as a force pump for throw` ying a constant stream of water to agreat i l "Hheight rdistance, for the purposes of eX- tinguishingre, orof `washing windows or vehicles. l v x i `My invention fzconsists` inproviding the pump with what"I term'a fventilating air "vessel, whichis`an air vessel applied in the usual waybutufurnished ashereinafterdescribed with ai `screwed cap or some equivalent device by which itmaybe readilytventilated to prevent ,the air being confined therein,whentheffpump is merelywused for drawing water,`or may be `closed to confine""theair when it isvdesired to` discharge `the height or distance"Y"\stream. t i e el e l To enable thseskilled in the" art `to makescribeits construction and operation." i

On the wp 0f the air ves- -sel there is a screwed nozzle K, to which isfitted s mit O-r female screwed Cap J Whh `containsja piece a, of indiarubber 0r other packing at `the top for closing the top of the nozzlewhen thenut or cap J, is screwed "dem es Shawn in Fi l, andmakns the airvessel `perfectly atr tight.v Below the packing c, the nutor cap J, hasa number sides, which, when it is unscrewed or raised top of the nozzleK, serve to form a free `cornrnunication between the air vessel andsurrounding atmosphere. This last -described condition of the air vesselis shown in Figa 2 i l o] make the pump `a common lifting pump, thespout I, has'to bel attached and the nut or cap J, unscrewed as shown inFig. 2 to ventilate the air' vessel; but to make it a force pump in caseof lire, or to throw a constant stream or jet of water to a distance orwith force, the spout is taken 0H and the hose substituted, and the nutor cap J, screwed down. Thus it will be seen that the air vessel F,having its discharge at or near the bottom, is convertible with facilityand despatch into a simple open water reservoirby slightly turning onlythe perfo-rated nut or valve arrangement J at the top as represented inFig.`2 of the drawing, when the valve J being open, the air in the spaceabove the water in the vessel F, having free egress through theperforations b b, is restrainedfrom 'compression during the lift inworking the pump which, under this open condition of the air vessel F,acts as the ordi- 1 nary,` well or lift pump in giving an easy fallingdischarge of the water, which for domestic uses and so forth isgenerally much more suitable or desirable than a forcible or strongiitful or jerking discharge would be as would take place were the airvessel F kept closed and the air above the water therein" exposed tocompression; though culiar or particular domestic use be required, thisis quicklyand easily obtained by simply closing the valve J at the topof the air vessel; or another convenient (for some purposes) mode ofworking may be adopted with equal mouth of the spout I and continuing'to Pump water,

when a prolonged discharge may be `of small perforations or holes ib, b,in its` far enough to raise the packing a, from the i should such aforcible discharge for any pe-v facility, by closingiup with the handthe till the air vessel F be filled with obtained without furtherpumping by removing the hand .from the mouth of the spout I, and thisdischarge made slow or quick by opening or closing the Valve J at top,at pleasure. Thus many conveniences are effected by this arrangement,and the facility and rapidity with which the common house or well pumpmay be converted into a force pump for extinguishing fires and so forth,by screwing down or closing the Valve J and screwing or fitting the hoseH on to the discharge as specified and represented in Fig. l, makes thearrangement yet more serviceable.

In no case, it should be observed, is the neck or nozzle K, at the topof the air vessel, meant as a discharge opening for the water; and thevalve or perforated nut J fitted thereon is purely an air valve,designed to be opened or closed at pleasure by the hand, to make the airvessel F a close one, or to convert it into a mere open water reservoir,accordingly as the pump is required to work as a common lift one, toproduce a free and easy discharge, or as an ordinary forcel pump, `toproduce a violent discharge, as specified; and herein exists thedifference between this arrangement and the many other Well known formsof pump using a close air vessel sometimes with the discharge pipepenetrating the top and descending into the interior of the air vesseland sometimes with the discharge outlet or spout situated below asspecied.

That I claim as new and useful herein, and desire to secure by LettersPatent, is-

The combination and arrangement with the air chamber or vessel F of thepump having its delivery spout or outlet below or at or near the bottomof said chamber sub stantially as shown and described, of a hand airvalve, or perforated nut J at or near the top of the air vessel, for theconversion by hand with facility and despatch of the close air vesselinto an open water reservoir, or vice versa, above the discharge outletor spout of the pump; and whereby the uses of the common well or liftpump may be varied with despatch and its conveniences augmented asherein set forth.
